Some fonts with ligatures break font rendering in the script editor

After swapping Studio to use Berkeley Mono with ligatures, I experienced the following (very broken) font rendering. First image is the default Fira Mono studio font, the second is Berkeley Mono compiled with ligatures, and the third is Berkeley Mono compiled without ligatures.

I’m not entirely sure if there’s an available non-paid font to help reproduce this (given Berkeley Mono is paid); willing to perform requested debug steps and ask the font developer about handing over a TTF for debugging.

After gaining permission from the font developer to share the TTF files with Roblox staff, I am unfortunately magically no longer able to reproduce the issue. Not sure if a flag flipped or if it was Windows’ font rendering being as garbage as usual until a reboot or something else randomly fixed it.

Sounds like we’re all good here - thanks for the report! Going to close this out as ‘Fixed.’
